Authors: Emerson’s Alexandre Peixoto, International Society of Automation (ISA)’s Andre Ristaino Selecting, engineering, implementing, and operating a control system is a significant, long-term investment. Applying a defense-in-depth strategy to protect the process from cybersecurity risks is another significant, long-term investment that can be made more complicated if the inherent security features of the control system […]
Emerson’s Sergio Diaz and Alexandre Peixoto presented Best Practices for a Cybersecure SIS at the 2019 Emerson Exchange conference. Sergio opened that the goal of this presentation is to provide practical information to maintain a more defendable security posture for safety instrumented systems (SISs). Like control systems, defense in depth is an important concept for […]
Safety instrumented systems (SIS), which are designed to take the process to a safe state in trip conditions, come in several architectures with the basic process control system (BPCS). The SIS and BPCS can be totally separate, interfaced or integrated, yet separate. While the debate on which approach is best has been going on for […]
Cybersecurity remains high on the list of issues for process manufacturers and producers to grapple with. In this 4:38 video, DeltaV Cybersecurity, Emerson’s Alexandre Peixoto discusses ways that cyber defenses are incorporated into the DeltaV distributed control system (DCS). He opens describing the defense in depth strategies which includes four major focus areas: plant-level security, […]
